ObjectiveTo summarize the experience of 4 patients with a great saphenous venous graft patency after 15 years of postoperitive great saphenous venous sequential aortic coronary artery bypass grafting. MethodWe retrospectively analyzed the clinical data of 4 patients accepted great saphenous vein aortic coronary artery bypass graft under moderate hypothermia cardiopulmonary bypass from November 1989 to December 1992 year. There were 3 males and 1 female with a mean age of 48.3 years ranging from 40-58 years. We harvested great saphenous vein under groin 45-50 cm. The proximal and distal anastomoses were performed with parachute technique under two clamps technique. Coronary artery bypass graft was performed by two sequential grafts routinely. Aspirin was given through nasal tube 6 hours after operation. The risk factors of arteriosclerosis were controlled by patients themselves after discharge. ResultFour patients received coronary angiography in 15, 16, 18, and 21 years after surgery and the grafts and both proximal and distal anastomoses were patent. The patients lived about 20 years without angina. Conclusioncarefully dealing with the vein graft, taking sequential bypass grafting to guarantee parabolic curve and meticulous anastomosis are preconditional and necessary for long-term patency.
Trial Sequential Analysis (TSA), one kind of cumulative meta-analysis, is a method which introduces sequential analysis into traditional meta-analysis to avoid random errors (false positive or false negative outcomes) that occurred during repeated updates when traditional meta-analysis is performing. It is also applied to calculate required information size (RIS) of a firm conclusion. This study aims to summarize the proposal, fundamental theory, application software, and current limitation of TSA, and to clarify the advantages of TSA on the basis of detailed examples, in order to attract more attention of researchers and promote the methodological development of meta-analysis in China.
ObjectiveTo evaluate the short- and mid-term outcomes of sequential anastomosis and simple anastomosis of saphenous vein in off-pump coronary artery bypass grafting.MethodsThe clinical data of 438 patients who underwent sequential anastomosis of saphenous vein and 165 patients who underwent simple anastomosis of saphenous vein from 2015 to 2018 in Daxing Teaching Hospital were retrospectively analyzed. After propensity score matching, 130 pairs of patients were included in the sequential anastomosis group [78 males and 52 females, aged 60 (52, 68) years] and simple anastomosis group [80 males and 50 females, aged 61 (52, 70) years]. The short- and mid-term clinical outcomes were compared.ResultsThe two propensity score-matched groups had similar baseline clinical data. No significant difference was found between sequential anastomosis and simple anastomosis groups in the in-hospital outcomes, including in-hospital death (1.5% vs. 1.5%, P=1.000), the incidence of complications (4.6% vs. 6.2%, P>0.05), and the mean flow of grafts (30.0±11.8 mL/min vs. 28.0±9.5 mL/min, P=0.597). The operation time of the sequential anastomosis group was shorter than that of the simple anastomosis group (142.5±21.2 min vs. 186.3±27.6 min, P<0.001). The drainage of the sequential anastomosis group was less than that of the simple anastomosis group (204.7±39.6 mL vs. 271.3±48.3 mL, P<0.001). The follow-up time was 12-60 (28.3±8.9) months, during which the mortality of the two groups was not statistically different (3.2% vs. 4.0%, P=0.796).ConclusionThe saphenous vein sequential anastomosis of saphenous vein is superior to the simple anastomosis. Sequential anastomosis technique can reduce aortic anastomosis, shorten operation time, and reduce bleeding drainage during off-pump coronary artery bypass grafting. The short- and mid- term clinical effects are satisfactory.
Objective To explore the effect of sequential nutritional intervention mode on improving early postoperative nutritional status in patients with gastric cancer. Methods A total of 30 patients who underwent radical gastrectomy for gastric cancer in the Department of Gastrointestinal Surgery, Ningbo No.2 Hospital between June and August 2022 were selected as the tiral group by convenience sampling, and another 30 patients who underwent radical gastrectomy for gastric cancer between September 2021 and January 2022 were retrospectively selected as the control group. The trial group received the sequential nutritional intervention model constructed by quality control circle activities in the Department of Gastrointestinal Surgery, and the control group received routine nutritional support. The nutritional status and quality of life of the two groups were evaluated one month after discharge. Results Before intervention, there was no statistically significant difference in the Patient-Generated Subjective Global Assessment (PG-SGA) score, serum albumin, serum prealbumin, body weight, or Quality of Life Questionnaire Core 30 (QLQ C30) score between the two groups (P>0.05). After intervention, both groups showed improvements in PG-SGA score, serum albumin, and serum prealbumin compared to before intervention (P<0.05); there was no significant change in body weight in the trial group (P>0.05), while the control group experienced a decrease in body weight (P<0.05); the trial group showed an improvement in QLQ C30 score (P<0.05), whereas the control group did not show significant change in QLQ C30 score (P>0.05). Compared to the control group after intervention, the trial group showed better PG-SGA score (7.97±1.65 vs. 8.83±1.26), serum albumin level [(40.61±1.30) vs. (39.93±0.78) g/L], serum prealbumin level [(0.266±0.030) vs. (0.229±0.051) g/L], body weight [(63.12±7.39) vs. (58.17±9.18) kg], and QLQ C30 score (62.63±9.01 vs. 57.23±7.13), with all differences being statistically significant (P<0.05). Conclusion Sequential nutritional intervention model is helpful to improve the early nutritional status and quality of life of patients after radical gastrectomy, and has clinical promotion value.
Objective To detect the false-positive results of cumulative meta-analyses of Cochrane Urology Group with the trial sequential analysis (TSA). Methods The systematic reviews of Urology Group of The Cochrane Library were searched to collect meta-analyses with positive results. Two researchers independently screened literature and extracted data of included meta-analyses. Then, TSA was performed using TSA software version 0.9 beta. Results A total of 11 meta-analyses were included. The results of TSA showed that, 8 of 11 (72.7%) meta-analyses were potentially false-positive results for failing to surpass the trial sequential monitoring boundary and to reach the required information size. Conclusion TSA can help researchers to identify the false-positive results of meta-analyses.
ObjectiveTo investigate the effectiveness of debridement-vacuum sealing drainage (VSD)-modified external fixation antibiotic-impregnated cement semi-open technique in treatment of chronic ulcer wounds. MethodsClinical data of 43 patients with chronic ulcer wounds who met the selection criteria and admitted between January 2019 and June 2023 were retrospectively analyzed. Among them, 23 cases were treated with debridement-VSD-modified external fixation antibiotic-impregnated cement semi-open technique (improved group), and 20 cases were treated with debridement-VSD-traditional antibiotic-impregnated cement technique (control group). There was no significant difference in gender, age, constituent ratio of patients with type 2 diabetes mellitus, constituent ratio of patients with smoking history, body mass index, wound site, and other baseline data between the two groups (P>0.05). The healing quality and healing time, the positive rate of bacterial culture after bone cement coating, the loosening rate of bone cement, the number of operations, the number of hospitalizations, the length of hospitalization, and the cost of hospitalization were recorded and compared between the two groups. Results Compared with the control group, the positive rate of bacterial culture after bone cement coating and the loosening rate of bone cement in the improved group was significantly lower, as well as the number of operations, the number of hospitalizations, the length of hospitalization, and hospitalization cost significantly reduced (P<0.05). Wound repair was completed in both groups without amputation. The wound healing quality of the improved group was better than that of the control group and the wound healing time was shorter, the differences were significant (P<0.05). All patients were followed up 1-5 years (mean 3.4 years), and no ulcers recurred during follow-up. ConclusionDebridement-VSD-modified external fixation antibiotic-impregnated cement semi-open technique in the treatment of chronic ulcer wounds can effectively reduce the loosening rate of bone cement, facilitate the induced membrane formation and wound healing, and significantly reduce the number of operations and shorten the length of hospital stay.
Objective To investigate the clinical significance of lateral position ventilation in the treatment of invasive ventilation in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Methods From October 2014 to December 2016, 60 eligible patients with AECOPD who meeting the inclusion criteria were randomly assigned to an intervention group (n=30) or a control group (n=30). Expectorant, antiasthmatic, anti-infective, invasive ventilation, bronchoscopy, analgesic sedation, invasive-noninvasive sequential ventilation, nutritional support, intensive care and other treatment were conducted in two groups, but lateral position ventilation was subsequently performed in the intervention group and the control group used half lateral position. Outcome measurements included pH, PaO2/FiO2, arterial partial pressure of carbon dioxide (PaCO2), heart rate (HR), respiratory rate (R) and air way resistance (Raw) before and one day after invasive ventilation, and duration of control of pulmonary infection (PIC), invasive mechanic ventilation (IMV), mechanic ventilation (MV) and intensive care unit (ICU) stay. Results Compared with before ventilation, the levels of PaO2/FiO2, PaCO2, HR, R and Raw were significantly changed in two groups after ventilation (P<0.05). One day later after ventilation, pH [interventionvs. control: (7.43±0.07) vs. (7.37±0.11)], PaO2/FiO2[(253.52±65.33) mm Hg (1 mm Hg=0.133 kPa) vs. (215.46±58.72) mm Hg] and PaCO2 [(52.45±7.15) mm Hg vs. (59.39±8.44) mm Hg] were statistically significant (P<0.05), but no significant difference was found in HR, R or Raw between two groups (P>0.05). Compared with the control group, PIC [(3.7±1.4) daysvs. (5.3±2.2) days], IMV [(4.0±1.5) days vs. (6.1±3.0) days], MV [(4.7±2.0) days vs. (7.3±3.7) days] and ICU stay [(6.2±2.1) days vs. (8.5±4.2) days] were significantly decreased (P<0.05) in the intervention group. Conclusions In AECOPD patients, invasive ventilation using lateral position ventilation can significantly improve arterial blood gas index, decrease Raw, shorten the time of PIC, IMV, MV and ICU stay.
ObjectivesTo systematically review the association between the SIX6 gene rs10483727 mutation and primary open angle glaucoma (POAG).MethodsPubMed, Web of Science, The Cochrane Library, CNKI, WanFang Data and VIP databases were searched to collect case-control studies on the SIX6 gene rs10483727 polymorphism and primary open angle glaucoma from inception to December 28th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by Stata 12.0 software.ResultsSeventeen case-control studies in 16 papers were included, involving 9 886 patients and 19 663 controls. The results of meta-analysis showed that rs10483727 polymorphism in SIX6 gene was associated with the risk of POAG in the Asians and Caucasians. However, no association was found in the Africans.ConclusionsThe current evidence shows that rs10483727 polymorphism in SIX6 gene is associated with the risk of POAG in the Asians and Caucasians.
Objective To explore the feasibility and effectiveness of perforator propeller flap sequential transfer technique in repair of soft tissue defect of distal lower extremity. Methods Between July 2015 and July 2021, 10 patients with soft tissue defect of distal lower extremity were treated with perforator propeller flap sequential transfer technique. There were 8 males and 2 females, with a median age of 47 years (range, 6-71 years). The etiologies included malignant tumor in 5 cases, trauma in 3 cases, postburn scar contracture in 1 case, and diabetic foot ulcer in 1 case. The defects were located at the pretibial area in 1 case, the distal lower extremity and Achilles tendon in 3 cases, the dorsum of foot and lateral malleolar area in 4 cases, the heel in 1 case, and the plantar foot in 1 case. The size of the defect ranged from 5 cm×3 cm to 8 cm×8 cm. Peroneal artery perforator propellor flaps (the 1st flap) in size of 14 cm×4 cm to 29 cm×8 cm were used to repair the defects of distal lower extremity. The donor site defects were repaired with the other perforator propeller flaps (the 2nd flap) in size of 7 cm×3 cm to 19 cm×7 cm. The donor site of the 2nd flap was directly closed. ResultsAll the operations were successfully completed and all of the 2nd flaps were elevated within 1 hour. Eight the 1st flaps survived completely; 2 had venous congestion. Among the 2 patients with venous congestion, 1 had necrosis of the distal end of the flap, and the secondary wound was repaired by skin grafting; 1 recovered spontaneously after 7 days. The 2nd flaps totally survived. No complication such as hematoma or infection occurred. Primary closure was achieved in all the recipient and donor sites. All patients were followed up 2-39 months, with a median of 15.5 months. The color, texture, and thickness of the flaps matched well with those of recipient sites. The normal contour of the leg was preserved. During follow-up, no recurrence of malignance or ulcer was observed. The scar contracture was completely released. All patients were satisfied with the reconstructive outcomes. Conclusion The application of the perforator propeller flap sequential transfer technique can improve the repair ability of the lower extremity perforator propeller flap while ensuring the first-stage closure of the donor site, thereby improving the effectiveness.
